Like a haunting coda for the love song to all the TF universes, The "Transformers Animated: The Complete Allspark Almanac" wraps up the TFA legacy nicely.

It's a massive TPB with gorgeous, colorful pages that are teeming with so much information its like getting an Allspark shard shoved into your brain (in a good way).
My favourite is how the character summaries are told from the perspective of fellow characters (i.e., Ultra Magnus discusses Optimus Prime)
Also cool are chapters dedicated to characters / situations / toys that were planned but never got to be onscreen.
A definite must have for any TFA fan!
